Problems solved by technology

If one font resolution is defined as 12*18 pixels, then 269 fonts are required to display a 636*90 pixel logo, then 7,155 bytes are required for monochrome fonts, 57,240 bytes are required for color fonts, and the screen The font memory of the display device 1 is only 6,144 bytes, so it is limited to 540*90 pixels, so part of the area 4 of the text or logo 3 cannot be displayed

Abstract

The invention discloses an image processor, a font screen display device and a display method. The method comprises the following steps: segmenting a text image to be displayed into a plurality of fonts according to the predetermined font resolution; classifying the plurality of fonts to form a plurality of classified fonts and storing a monochromatic font or a colorful font corresponding to each classified font into a font memory, wherein each classified font corresponding to a linear font is the monochromatic font, and each classified font corresponding to a nonlinear font is the colorful font; establishing a font and position corresponding relation of each classified font in the text image and storing the font and position corresponding relation into a storage media; and displaying the text image on a display through the classified fonts stored in the font memory and the font and position corresponding relation stored in the storage media. The font screen display device and the display method have the beneficial effects that the use of the storage space of the font memory can be reduced, and the system resources of the screen display device are saved.

Description

technical field [0001] The present invention relates to an image processor, a character-type screen display device and a display method, in particular to a screen display device and a display method capable of displaying a character image with a relatively high resolution on a display. Background technique [0002] On-screen display (OSD, On-screen display) is applied to flat-panel displays, such as CRT or LCD displays, to generate text or graphics on the screen of the display, so that users can get some information, and become an important information generation device on the human-machine interface . In terms of specific implementation, text is usually displayed in the form of a dot matrix. Among them, 8 bits in a byte represent a point, which is used to indicate whether the point is displayed, and a byte can represent 8 points. For text For example, if a 16*16 dot matrix display is used, the dot matrix data corresponding to the text needs to occupy 2*16=32 bytes, and if ...
